YouCare is a unique search engine designed for Firefox that allows users to contribute to charitable causes through their online searches. By using YouCare, each search can help with initiatives such as reforesting the planet, providing meals to shelter animals, and supporting cancer research. The platform operates on a free license and generates revenue through advertisements, which are then used to fund these charitable deeds. Users can discover various ways to support good causes simply by searching the web.

In addition to its charitable focus, YouCare emphasizes transparency and environmental responsibility. The service compensates for 100% of its CO₂ emissions by planting trees globally through partnerships with organizations like Eden Reforestation Projects. YouCare also prioritizes user privacy, ensuring that search history is not recorded and that all searches are encrypted. Monthly reports and photos from partner organizations provide accountability and showcase the impact of contributions.
